Too many issues
Apple spent millions developing their camera and software so why did I think this app could improve it? It has some cool features but overall I have more complaints than things I like. Compared to the native app, the audio is crap, my settings change back to default every time I start the app and the app is slow to start so you miss that "moment" waiting for the app to open. Definitely not worth paying for.
